Not Actually Up To You

So, nothing about this gun is "expected." But for it to turn what was once a barely legal slut into a gorgeous schoolgirl (and before that, a dude), complete with a scorching Catholic school uniform was definitely unexpected. Unexpected, but definitely not unwelcome. The schoolgirl look has always been an Achilles heel for me. The problem is, I still don't know what those body and character switches mean, and my hypothesis on the symbols Δ and π representing change and constant are wild guesses with no basis. I don't even know what setting the gun was on when Jack was morphed into Jackie.

As I sat there, going further and further down the hypothetical rabbit hole, my concentration was broken by the sound of a low, husky voice. "Oh there you are Mr. Johnson. I was hoping you weren't going to stand me up. It's really nice of you to offer to tutor me. I've just been having so much trouble focusing in school lately. My dad's almost never home, and my mom isn't the best teacher, so when she told me you'd offered to help me out, I was thrilled."

The gun and its variables are now secondary in my mind. This gorgeous blonde school girl is apparently here for a study session, with me. And I was focusing on what switches do what.

"Hey Jackie, sorry I got caught up doing something...upstairs...and didn't hear you come in. How are you doing"

"I'm doing okay, I guess, but it seems my favorite new neighbor doesn't even know my name is Jenni." She says as she lets loose a pout that suggest that there's still at least some remnants of Jackie in there.

Jenni, huh? Interesting. "I'm sorry Jenni, I'm not sure where my head was at. So, what subjects can I help you with?" I might not have planned to tutor anyone today, but damn it, I'm sure as hell not going to send this woman away if I can help it.

"Well, that's the thing," she started, "I'm actually pretty good at math, science and history. All my classes, really. Except one. And I think it is my frustrations in that class that are spilling over to my other classes."

"Well, that should make things easier. Which class is it?" As the words leave my mouth, I notice that Jenni doesn't appear to have any books or papers.

"Why Mr. Johnson, it's Sex Ed. You see, ever since you moved in next door to us I have had so much trouble focusing on school. Did you know my bedroom looks into yours? Did you know that you don't always close your curtains?" Sitting down on the couch, Jenni poses so as to give NO doubt about what she's getting at.

"Why Jenni, I had no idea! I'll make SURE to close my curtains from now on. Will that help your schoolwork?"

"That's not a viable solution to my problem, I'm afraid." Jennie says, as a predatory grin appears on her face. "You see, Mr. Johnson, after what I've seen, I'm going to have take some drastic measures." With that, she reaches forward, pulling you towards her by my belt with one hand, while unzipping my pants and fishing my engorged cock out with the other. "Hmmm...it's even bigger than I thought it was! I never really got a great look at it through our windows."

"Well Jenni, if you're going to take matters into your own hands like this, I think you should call me Mark." With that, I pull her to feet, freeing her tits from her uniform while she wiggles out of her panties. Reaching between her legs I found her hairless cunt to be sopping wet. Thrusting a finger into her folds elicits a deep moan from the blonde before me.

"Mmmmm...I've been so wet thinking about you. Ever since you moved in I wanted you, but when my mom told me you were going to tutor me, my cunt went into overdrive. I've never been this wet before in my life! Let's skip the preliminaries. I need your cock in my now!"

Having never been one to refuse a gorgeous woman's request, I push her back onto the couch and quickly doff what was left of my clothes. Despite being so hot and wet, Jenni's pussy is still incredibly tight. The fact that simply getting my cock head in sets off her first orgasm only seems to make her tighter.

"FUCKKK! I've never had anything close to this big inside me! Fuck going slow! Fuck me NOW!" She screams as she writhes under me.

This is no intimate coupling. This is a hard, fast, brutal fucking. Neither of us are anywhere close to coherent as I piston my cock in and out of her. Muttering and swearing as we thrust our hips towards each other's, both racing towards massive climaxes. I feel myself about to burst when Jenni reaches a orgasm, constricting my dick in delicious tightness. At the last moment, it occurs to me, it might not be best to cum in her. At least not on the first go round. "Jenni, I'm about to cum..."

"FACE! Cum on my face!" It's with no small measure of regret that you retract yourself from her snatch, I quickly move up to straddle her chest as she grasped my cock, feverishly pumping me towards my own orgasm. "Yessss..." she purrs as I launch rope after rope of jizz all over her face catching much of it in her mouth.

Completely spent, I collapsed on top of her, before rolling off the couch. As I catch my breath, my hand lands on the gun, discarded among the piles of clothes tossed around the living room. As the two of us pant heavily trying to catch our breath, I decide there's no time like the present. Mentally tossing a coin in my head, I flipped one of the switches, sit up, aim, and ZAP!
